I notice too that the opening in the bottom of an EF lens is about an inch in diameter while the opening in an EF-S lens is only about 0.7". The full frame lens, therefore, has more lens than a crop sensor can use. The speed booster compresses all of that larger lens onto the smaller sensor for obvious gains. Oli M is right, the EF-S lens has no extra capacity to benefit a crop sensor camera. Vignetting may be the least possible result. The compressed image from an EF-S lens may not even fill the sensor. ???
@@jimreminga7411 a good example is this is this video: ruclips.net/video/XsJUcTXGyJ8/видео.html he talks about the excellent sigma 18-35mm that everyone loves. However because the sigma is a cropped lens you will get vignetting from 18 to 28mm
LOL damn I wish I saw this two days ago before I ordered it. I just got it and was wondering why my ef-s lenses werent working. This makes sense! Thank you!
The Sigma 30mm f1.4 (to Canon) will fit on the Viltrox EF EOS M2 adapter. This lens was designed for crop sensor cameras. In my experience, the lens performs poorly (in terms of vignetting and sharpness at the edges) with the focal length reducer. In my experience this speed booster performs better with lenses that were designed for full frame sensors.
You can saw off the extra plastic on EF-S lenses to fit the speed booster, of course it will devalue the lens but if you plan on keeping them anyway you do a bit of surgery. There's videos online showing how to do it, if you can't find them when searching Eos-M mount, try looking at the M43 version of the Viltrox 'EF-M2' the hack for it is the exact same.
I did the same thing on the EF-S 55-250mm. You can't just pop out the protruding flange on that particular lens, so I whacked it off and works just fine on the EF-M2 II.
Why not try to cut off the extra plastic. Worth trying with a less expensive ef-s because if cutting it works then it's a big bonus for those of us using a speed booster. Do you want more subs? Take chances.
Wrong. Just remove the black protruding plastic EF-S element. Very easy on EF-S 18-135 STM or USM , and EF-S 17-55/2.8 IS USM . Literally takes only 4 seconds to modify the EF-S to EF mount on these 2 lenses. On other lenses a little bit of work/tools.
Good review! I just got mine today but confused about the aperture control actually. I have the same 50mm 1.8 ef for my eos m, I unstalled my viltrox to my lens and camera, my angle(mm) clearly expended, also realized that more light coming thru my sensor bc I have a regular glassles adapter to compare with viltrox. The thing is when you mentioned your nifty fifty goes f1.2, can you actually see the aperture number shows f1.2? Because I never get to see that number goes 1.2, it still shows lowest as 1.8. but slightly brighter then regular 1.8 lots of confusion here 😄
The samples I've seen of the Viltrox are very soft and I can't be certain attention to detail wad observed. Are you getting the same results? I want to make the purchase, but not at the expense of image quality. Thanks for the video lesson!
bagery I’m not a pro and my only full frame lens is the 50mm 1.8. At f1.2 images are softer than at f8, but I’m happy with the results. I bought on Amazon knowing that returns are easy. Give it a try.
I want to produce educational videos. I am debating between 6D MKii + 50mm1.4 vs M-50+Viltrox+50mm 1.4. Which way should i go? Would there be any difference in Bokeh between the two setups at their widest apertures?
I got this for my canon M50 because the Viltrox web site showed compatible with the EFS-M lens. When I got the Viltrox EF-EOS M2 and saw that it didn't fit the -M lens it went right back.
What is you put the Viltrox Speedbooster on you M50 with an EF-S lens, and shoot 4K video (which is cropped in 1.6 anyway). Do you still see vignetting, or does the crop factor eliminate it?
@@jimreminga7411 Ahh, I guess I got confused because this adapter does support the Sigma 18-35 F1.8, which I thought was an EF-S lens. This video explains it nicely. ruclips.net/video/XsJUcTXGyJ8/видео.html
Pete Berg the Sigma 18-35 will work in 4k with the speedbooster without vignetting, but will not work in regular 1080 due to vignetting. While the 18-35 is designed for crop sensors, it is an EF Mount, which is why it will work with the speedbooster, where as in this video it does show that EF-S lenses will not work due to the physical limitations of the EF-S Mount, and not necessarily the glass itself.
Thank you but on top of that why would you put a cropped lens on a speed booster which the goal is to extend to almost full frame. You will get vignetting anyway. Yes speed booster is for full frame lenses to get to most of it.
This is great man! I figured this out after seeing the difference between the EF and the EF-S. Thanks for the tip! You're awesome man.

Me too 😭😭
@MattMovieMaker what did you do after that? Did you buy the EF-M1?
Very informative. Stopped me from making a major mistake
This video solved a great issue for me, thanks a lot!

Thank you for this I was so confused why it wouldn’t work
Great explanation. Thanks
Well done thank you for the video.
Thank you for making this video... now to find the video of someone cutting that plastic piece
right? lol

The efs 18-135 all you do is extend it to 135 and the plastic piece pulls right off
Thanks so very much worked like a charm
Nice very helpful
👏👏👏 thx

It gives you the same light as f1.2 but the lens stays at its max aperture

straight and on point. Thank you. Very informative.
Where can you get this booster faster? I got it at Amazon and it's not shipping until Dec 23-Jan 15. Where did you purchase yours?
Davian's Dad I got mine on Amazon. It arrived in only 3 or 4 days, much faster than the ad said. Seller was Toazoe.
Will it accept the EF-M third party Laowa 9mm f/2.8 lens?
I got this for my canon M50 because the Viltrox web site showed compatible with the EFS-M lens. When I got the Viltrox EF-EOS M2 and saw that it didn't fit the -M lens it went right back.

Pete Berg The Viltrox does not accept EF-S lenses.

Can we use speed booster on canon 80d
Amit Bajracharya Mine is just for the M body mirrorless cameras.
No
